I just went to check out thrift books and found something surprising. I looked up an old childrens book that’s an old favorite of mine and saw a review that looked really familiar and triggered something in my mind. I went over to Amazon and found the exact same review...word for word. I wonder what’s going on here...does Amazon sell review text to other vendors? Is there a public API for reviews that other sites can use?
